BRICK-MOLD.

Specification of Letters Patent No To all whom it may concern: 7

Be it known that I, MAT'rr-Inw ELDER, of Lansing, in the county ofIngham and State of Michigan, have invented a new and ImprovedBrick-Mold; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings, which form a part of this specification, Fig. 1, being a topview of said briekmold; Fig. 2, a side view of the same; Fig. 8, an endView; Fig. 4, a longitudinal vertical section, in the line (1:, w, ofFig. 1; Fig. 5, a transverse section in the line 3 3 of Fig. 1, and Fig.6, a transverse section in the same line, representing the respectiveparts of said mold in a different position from that shown in the otherdrawings.

Similar letters indicate the same parts in each of the drawings.

I generally construct my improved brick- .old of such a size as to giveit six molding compartments; but do not intend to limit myself to thatparticular size. The compartment-frame of my improved brick mold, may beformed by the union of two outside longitudinal strips A, A, and acentral longitudinal strip 0, with the endpieces 13,13, and transversedividing strips D, D, in the manner represented in the drawings, or anyother that may be preferred.

The metallic clamps H, H, which embrace the outer corners of the saidcompartmentframe, add materially to its stiffness and strength; and theyalso serve other important purposes in the construction of my improvedbrick-mold, which will be hereinafter pointed out.

Through perforations near the outer angles of the corner clamps H, H,loosely receive the vertical rods a, a, whose opposite ends are rigidlyunited to the ends of the metallic cross-heads F, F, while the length ofsaid rods must be a little more than twice the depth of the moldingcompartments.

One end of a rod 6, is rigidly secured in an aperture in each of thecorner clamps H, H; and the shanks of these rods work freely inapertures in the ends of the cross-heads F, F; but are prevented frombeing drawn out said apertures by means of enlarged heads, asrepresented in the drawings.

A pair of light and stiff bars E, E, which pass longitudinally over thecenters of each 29,958, dated September 11, 1860.

side series of molding-compartments, when the compartment-frame is inthe position shown in Fig. tt, have their ends connected with thecross-heads F, F, by means of the short bolts 0, 0, whose shanks worklongitudinally in apertures which are formed in offsets on the inneredges of said cross-heads. The springs e, c, which are so arranged as topress the ends of the bars E, E, outwardly from the cross-heads F, F,serve the purpose of holding the followers G, G, in their normalposition until after the compartment frame has been elevated entirelyfree and clear of the sides and ends of the molded bricks, during theprocess of dis charging the same from the molding compartments.

The followers G, G, which work in the respective molding compartment ofthe compartment-frame, must be rigidly connected to the bars E, E; andthis may be done by means of the cross-headed arms (Z, Z,-shown in thedrawings or by any other suitable means. The said followers (Gr,) fit asclosely within the sides and ends of the compartments of thecompartmentframe, as is practically consistent with the free working ofsaid followers through the said compartments; and a suitable number ofconical apertures i, z', are formed in the said followers, to allow theair to escape freely from the molding compartments during the process offilling the same with tem pered clay.

Fig. 6, of the accompanying drawings represents my improved brick-moldas in the proper position for receiving tempered clay into therespective compartments of said mold; and when thus placed, it shouldrest upon a molding-board, or upon some other firm and level surface.The compartment-frame, when the brick-mold is in the aforesaid position,rests firmly upon the corner-rods 6, Z); and the series of followers G,G, rest upon the short bolts 0, 0. After the respective compartments ofthe brickmold have been evenly filled with properly tempered clay, thesaid mold is removed to the brick-yard and placed, in a reversedposition, upon the hard, smooth, and sanded floor of the same. Then, thebearer rests the palms of his hands upon the offsets f, f, of thecross-heads F, F, and at the same time places his fingers beneath thehandles g, 9, that project outwardly from the ends, B, B, of thecompartment frame: and then,

by hearing down with the palms of his hands, he causes the cross-headsF, F, the

bars E, E, and the followers G, G, to rest firmly and immovably upon therods a, a, while, by the action of his fingers, he raises thecompartment-frame entirely free and clear from the sides and ends of themolded bricks: and then, by a slightly increased additional exertion offorce upon the said compartment-frame, he overcomes the action of thesprings e, e, and thereby draws the followers G, G, smoothly from theupper surfaces of the said molded bricks. By following the aforesaiddirections in using my improved brick mold, it will be perceivcd that,without the exercise of any art or skill on the part of the operator, itwill be impossible for him to injure a molded brick by the operation ofdischarging the same from its molding compartment; as he is compelled todraw the sides and ends of the molding compartments from the moldedbricks in a line which is at right angles to the top and bottom of eachbrick; and he is also compelled to entirely remove the sides and ends ofthe said molding compartments, from the sides and ends of the moldedbricks, before he draws the followers from the upper sides of saidbricks.

The principle of this, my improved brickmold, may also be applied in themolding of tiles and other similar articles.

Having thus fully described my new and improved brick-mold, what I claimtherein as my invention and desire to secure by Letters Patent, is

l. The arrangement of the compartmentframe and the respective followersG, G, with the pairs of rods a, a, and b, b, the cross-heads F, F, theshort bolts 0, c, the longitudinal-bars E, E, and the connectingarms d,d, in such a manner that the said compartment-frame can be entirelywithdrawn from the sides and ends of the molded-bricks, while thefollowers remain stationary, substantially in the manner herein setforth.

2. The interposition of the springs e, e, or their equivalents, betweenthe cross-heads F, F, and the ends of the longitudinal-bars E, E, whenthe said parts bear such a relation to the other parts of my improvedbrick-mold, that the followers G, G, will remain stationary, while thecompartmentframe is being drawn past them, and then, the said followersand frame, may be simultaneously elevated a short distance, while thecross-heads F, F, remain in a stationary position upon the rods a, a; bywhich I effect a clear and clean separation of the compartment frame andthe followers from the molded bricks substantially in the manner hereinset forth.
